The Product Tester - Chapter 11

 Illustration by the fantastic HofBondage. 

Mary was left alone for a solid five minutes, wondering what exactly was going on, piecing it all together in her head. 

Kat had mentioned a safe word. That was a thing for, like… sex stuff. But the diaper cover was involved, and she was supposed to have a babysitter coming to attend to her…

It painted a picture in her mind, but not a pretty one. 

Before she could start to get uncomfortable in her restraints, a woman walked in. She was pretty, and she was dressed… rather like a stereotypical housewife. The hem line was perhaps a little lower cut than was usual, but the sundress and half apron she wore screamed ‘traditional matron figure’. 

She shut the door behind her, stepping up to Mary with a sweet little smile. “Hello, little one. I’m Rebecca, it’s so nice to meet you.” 

“I, um…” Mary started to say, uncertainly. “Hello, Rebecca.” 

“Now,” Rebecca said. “I heard that you are a very naughty little girl. A little birdie told me you think you’re too big for your diapers. We both know that’s not true, of course, but that doesn’t mean you should get to go telling fibs, should you?” 

Mary was just confused now. “I’m… sorry?” 

“Oh, you will be,” Rebecca beamed. “Now, what would you like me to call you?” 

“Erm… Mary, I guess.” 

“Alright, Mary,” Rebecca walked up to her, adjusting her cover and removing it with a handheld scanner that deactivated the lock. Pulling it aside, she hung it up on a hook on the wall, giving her access to Mary’s diaper. “Oh my, this is quite soggy. You had more than a few little accidents, didn’t you?” 

“I don’t know, I guess?” Mary said. What’s her game? 

Rebecca giggled. “Of course. Little ones can’t even tell when they’ve had accidents.” 

Untaping the diaper, she maneuvered a foot behind the table, pulling out a diaper pail and lifting the lid so that she could throw the sodden garment away. 

Then, she stepped back to the table, picking up another object that had a roughly similar shape to the diaper cover. It was all stainless steel, and though Mary didn’t recognize it on sight, she could easily guess at its purpose. 

“Do you know what this is, little Mary?” Rebecca asked, as though she were asking a child if they recognized a toy. 

“It’s a… chastity belt, right?”  

“That’s right.” Rebecca smiled, fluttering her eyelashes prettily. “Once you leave this room, you’re going to be wearing this chastity belt. You don’t get a choice in that. However, I’m going to make you a little deal, little one.” 

“What’s that?” Mary tilted her head. 

Setting the chastity belt aside, Rebecca picked up a magic wand, using it to gesture. “I’m going to play with you. If you get through all of our playtime without asking to cum, then for the rest of the weekend, you can have a diaper change whenever you ask for one.”

“But…?” Mary asked, sensing a catch. 

“But,” Rebecca confirmed. “If you want to cum, you will tell me that you’re a little diaper whore who never wants to use the potty. You’ll get what you want, and you won’t get a single diaper change for the rest of the weekend.” Stepping close, dropping her tone, she added, “You’ll have to stay in the same smelly, sticky diapers until we let you go.” 

That was a fairly easy decision. Mary would just not ask to cum. It wasn’t complicated in the slightest. 

‘Uncomplicated’ wasn’t the same as ‘easy’. Moving her body closer to Mary, her dress shifting a little, Rebecca’s free hand drifted down between Mary’s legs, and slowly, sensually, she began to play. 

…

“Where’s Mary?” Ethan demanded into the receiver. 

Katherine paused on the other end of the line, doing her best to sound genuinely confused. “How could I possibly know that?” 

“I don’t- You know something you’re not telling me.” He was pacing the apartment, taking long, deep breaths. “I did an emergency request for her GPS locations. The night she stayed out late and missed her evening change, she was at the office.”

“Was she?” Kat asked, her tone innocent and saccharine.

“Cut the shit. I’m not stupid enough to believe it was a coincidence that you fucked with my hours the next day. Where is she?” 

That took Katherine aback. She wasn’t surprised that Ethan had pieced it together - it was an easy thing to logic through, once he had the GPS information. She’d never heard him swear, though, not in the five years he’d been working for her. 

“Fine. I was feeling vindictive that she broke into our servers so I decided to get her back. Would you rather I called the police on her for trespassing?” 

Ethan wasn’t having it. “If Mary gets hurt-”

“Mary is fine.” 

“So you know where she is? What aren’t you telling me?” 

Kat sighed. “Mary is fine, because Mary is a smart, clever, resourceful woman who wouldn’t just drive off into danger for no good reason.” 

“Hmm.” 

“You disagree?” 

“No, but I know you’re not telling me everything.” 

Kat rolled her eyes. “You’re one to talk about being open. Have you told her yet?” 

“That’s not- That doesn’t matter,” Ethan said, flustered by the unexpected question.

“You mean you’ve been changing her diapers for most of a month now, and she still doesn’t know? Ethan, that’s-”

“I’m hanging up now. If you find her, call me right away.” 

The phone clicked, and Kat sat back in her chair, satisfied. 

…

“Oh, oh god, don’t stop, don’t-” Mary whimpered. She’d been reluctant at the start, but as Rebecca’s fingers teased her with incredible delicacy, her trepidation had melted away. 

For the third time in a row, Rebecca pulled away just as Mary reached the edge, leaving her frustrated and desperate. “You know what you have to say, little one,” she teased. 

Mary groaned, but she shook her head. 

Sighing, Rebecca stepped away for a moment. “We’re in this for a while then, I see. I suppose we’ll need to take a few… precautions.” 

Squirming, Mary futilely tried to get a little more pleasure, but there was nothing for her grind against. Without Rebecca’s touch to make her melt, there wasn’t anything she could do. 

Rebecca was content to take her time. She unfolded a puppy pad and slid it beneath the base of the table Mary was cuffed to, to prevent any leaks. While she was down there, she took a pair of booties, slipping them onto Mary’s feet with quick little motions. 

They felt odd, though it took a moment for Mary to place why. The soles weren’t just soft fabric like she’d expected, they were shaped, curved slightly, so that they slipped and slid no matter how Mary tried to put her weight on them. She had the table to support her for now, once she was standing, it’d be particularly difficult to walk with them. 

Next, came a pair of matching pink mittens, which slipped over Mary’s wrists and pulled tight. The purpose of those was more obvious - as long as the mittens were on, Mary’s hands would be all but useless. 

Finally, Rebecca leaned into Mary, their bodies close, and reached between her legs once again. This time, though, she went further back, and Mary gasped when she felt a slick, lubed-up tip of hard rubber play at her backdoor. 

Rebecca went slowly, using gentle force, teasing Mary open until the whole plug went in. It wasn’t enormous, but it was wide, and heavy, and Mary couldn’t ignore the feel of it taking up space inside her. 

“There we go,” Rebecca said, her tone almost a coo. “No more worries about your little accidents, or your little fingers or toesies getting hurt. Now, where were we?” 

Reaching down, her thumb and index finger teased at Mary’s clit, making her breath catch. Taking that as a good sign, Rebecca moved a little lower, one of her fingers probing inside.

Mary tensed, and shook her head. “W-wait, no-” 

Noticing the change in mood, Rebecca pulled away immediately. “What is it?” 

“I don’t…” Mary frowned, shaking her head. “Nothing inside, while I’m tied up.”

“Oh,” Rebecca smiled, her tone soft. “Of course, little one. Whatever makes you comfortable.” Looking Mary up and down, she added, “Well, not too comfortable, but you know what I mean.” 

Mary felt unsure of herself. In her head, none of this was a good thing - she didn’t think she should want to be cuffed at all, having this woman tease and play with her, trying to goad her into begging for humiliation. And yet, despite knowing the safe word to let herself out in a second, Mary had only balked at one thing. 

I don’t like this. I shouldn’t like this. So why-

Her train of thought was abruptly derailed by a sudden vibration from the plug. It was unexpected, but… not unpleasant.

“I don’t want to stay in the same diaper,” Mary whimpered. “P-please.” 

“You don’t have to, dear. That’s your choice.” Rebecca held up a remote, very deliberately pressing a button on it, and the plug inside Mary buzzed faster, more intense. 

Mary’s breath caught, and Rebecca brought her to the precipice of pleasure once again, never quite letting her go over the edge. 

Would it be so bad? She considered. It’s only a few days. You went twenty four hours before, when-

Catching herself, Mary shook her head. There was no way she would agree to that sort of humiliation, just for a brief moment’s pleasure. Even so, as the plug thrummed and pulsed with vibrations, as Rebecca’s fingers slowly teased their way inside her… she couldn’t help but wonder. 

Opening her mouth to gasp, she was surprised to feel Rebecca’s fingers playing against her lips, her other hand no longer free. Instinctively, without needing any guidance or direction, Mary closed her lips and sucked on her fingers, and as a reward for her obedience, Rebecca thrust her other hand deeper inside Mary. 

Helpless to do anything else, Mary moaned, drool dripping down her chin. “P-pweath,” she begged around the fingers on her tongue, praying that Rebecca might have a streak of mercy. 

“Just give in, sweet thing,” Rebecca whispered in her ear. “Just tell me you don’t want to change, that you would love to be my stinky, helpless little slut, trapped in your own accidents, only able to fantasize, play, and fill your padding. That would be nice, wouldn’t it?” 

Every phrase was emphasized by a little more sensation, a little more pleasure, and Mary found herself inclined to agree. “Y-ye-” 

And then, the pleasure vanished. The buzzing stopped, and Rebecca pulled both her hands away. Mary whimpered, kicking her bootie-clad feed, and her babysitter laughed. “Oh, I’m not ready for you to say yes just yet, little Mary. It’s good to know how easy you are, though.” 

“You are horrible,” Mary groaned. “I hate you.” 

“Aww, you’re just feeling fussy,” Rebecca teased. Turning her back, she walked over to the table, picked up the wand, and flicked it on. It began buzzing in her hand, and she returned her attention to Mary. “I think I know just what you need.”

…

Ethan leaned in over his keyboard, typing away. There had to be something he was missing. 

Mary couldn’t have just blocked out the wireless signals from the collar. He’d set them up himself. Four redundant systems, with two separate transmitters. If they weren’t all blocked at the same time, they’d sent up a warning signal immediately showing a signal loss. 

Besides that, though, he didn’t know how Mary planned on removing the cover without hurting herself. Without GPS, tracking, or any sort of signal, there was only a solution he could think of, but it was terrifying. 

She’d have to hole up in a hotel room or a friend’s house, and repeatedly activate the shock collar, the drugs, and the other countermeasures until they were all exhausted. Mary would basically be torturing herself for days, and he knew she was stubborn enough to do it. 

As far as Ethan was concerned, she’d won. And now, she was going to put herself through hell to prove it. He didn’t even want to think about the suffering she was going through. 

…

“F-f-fuck!” Mary whimpered, as another wave of pleasure rolled through her body. “Don’t stop!” 

…

I should never have let her do this, Ethan thought. It was absurd - he couldn’t have stopped her - but he still felt responsible.

Or, rather, Kat was responsible. She’d done this on purpose. She’d brought Mary in, gotten her in this position, gotten her in trouble. 

If I’d just told her the truth-

Ethan shook his head, tabbing through information about the cover. Marketing plans, distribution, potential markets. 

Mary had never been given the full story. They were making a version of the cover for nursing homes, sure, but that was a half truth. That version would only feature the lock and the safety features. No shocks, no collar, nothing that could potentially hurt the patients. 

Ethan tabbed to the next menu. The sales pitches they’d put together for various Corrections Departments, as a punitive alternative to ankle monitors. That would be the biggest market, if they could sell enough legislators on it. 

But, it wasn’t the only other market. 

Tabbing through, Ethan looked at the idea that’d gotten this whole project started. 

Sales to niche fetish communities. 

Project Impound hadn’t started as a business opportunity. Ethan had been working on his off hours, reading up about a new variety of kevlar that the company was developing. He’d gotten thinking and, on a whim, put together a rough sketch for a diaper cover using the material. 

It was a silly idea, made more out of fantasy than any intention of actually producing the design. The original sketch had a big steel padlock hanging from the front. 

But, like an idiot, he’d saved the project on his work computer. When he’d clocked in the next day, Kat had been waiting for him in his office. 

When he was busted, he’d initially imagined he was going to get fired. Instead, Kat was on board. She understood the kink angle, but she hadn’t given him crap about it - instead, she asked about possible sales opportunities, practicality, cost. She’d thought about it like a CEO, and asked him to draft up a real proposal. 

Project Impound had been born, out of a kink he’d never wanted anyone to find out he had. 

That was supposed to be the end of it. It was a work project. Mary didn’t need to hear about it. 

But then, Kat had gone and dragged his fiance into it. 

And now she was missing, and in danger. 

And if Ethan had just been honest, none of this would have ever happened. 

I’m such an idiot. 

…

Mary panted. She’d been on the precipice of an orgasm for longer than she could count. Five minutes? Ten? Is time even real?

“Just say it, little one,” Rebecca whispered in her ear. “You know it’s true.” 

“I-” Mary stammered. I can’t take it anymore. She couldn’t remember the exact words, but she improvised, doing her best to satisfy her babysitter. “I’m- I’m a little diaper slut. P-please, just let me use diapers, I never want to use the toilet again, I don’t want to change, j-just… just let me-” 

The wand pulled away. The plug stopped buzzing. Rebecca stepped back. “See? I knew it was true. Doesn’t it feel nice to admit it?” 

Mary stared, her frustration making her whole body feel tense and full of energy. “Huh? Why’d you-” 

“I never said you’d get to cum, little Mary,” Rebecca smirked. “I said you’d get what you want. And you just made it very clear to me what you want.” 

“No,” Mary shook her head. “No, wait. That’s not what I want at all!” 

Rebecca rolled her eyes. “We both know that’s not true, little baby.”

Setting down the wand, she picked up the chastity belt, approaching Mary with malice and amusement dancing in her expression. Mary stammered, squirmed, tried to think of a way out of it, but nothing came to mind. She was helpless. 

Gently removing the plug, Rebecca set it aside, slipped the cage up between Mary’s legs, and buckled it in. She didn’t have to lock it - the point was to provide a barrier to sensation. Mary wouldn’t be able to remove it regardless. 

Rebecca locked it anyways, so that Mary could hear the little ‘click’ as her chance of satisfaction was locked away. 

“Now,” Rebecca cooed. “You’ve got a whole weekend ahead of you, and we certainly don’t want you to leak. Let’s get that taken care of.” 

Mary swallowed, her throat dry. What did I get myself into here? 

And yet, at the same time, she shuddered with excitement. And what comes next?
